Objective To discuss the diagnosis and treatment of pulmonary contusion. Methods A retrospective study was carried out in 132 cases of severe pulmonary contusion (injury severity score ≥20) from February 1993 to December 2003. Results Of all, 107 cases (81.1%)survived and 25 (18.9%)died. Conclusions Chest X-ray and CT are reliable for the diagnosis of pulmonary contusion. The important methods include keeping airway clear, progressively treating shock and reasonably applying ventilation, steroids as well as antibiotics. The early diagnosis and the prompt treatment of the associated injuries are key to higher cure rate.

The aim of this study was to propose an algorithm for three-dimensional projection onto convex sets (3D POCS) to achieve super resolution reconstruction of 3D lung computer tomography (CT) images, and to introduce multi-resolution mixed display mode to make 3D visualization of pulmonary nodules. Firstly, we built the low resolution 3D images which have spatial displacement in sub pixel level between each other and generate the reference image. Then, we mapped the low resolution images into the high resolution reference image using 3D motion estimation and revised the reference image based on the consistency constraint convex sets to reconstruct the 3D high resolution images iteratively. Finally, we displayed the different resolution images simultaneously. We then estimated the performance of provided method on 5 image sets and compared them with those of 3 interpolation reconstruction methods. The experiments showed that the performance of 3D POCS algorithm was better than that of 3 interpolation reconstruction methods in two aspects, i.e., subjective and objective aspects, and mixed display mode is suitable to the 3D visualization of high resolution of pulmonary nodules.

OBJECTIVETo evaluate the diagnostic value of serum miR-103 for breast cancer and its correlation to the clinicopathological features of the patients.

METHODSWe collected the serum samples and corresponding formalin-fixed paraffin-embedded (FFPE) surgical specimens from 50 breast cancer patients, using the serum samples from 50 healthy women as the control. The total RNA was extracted from the samples for quantitative analysis of miR-103 using real-time RT-PCR.

RESULTSThe serum levels of miR-103 expression were significantly higher in the cancer patients than in the healthy control group (P<0.01). In the cancer patients, high miR-103 expression was significantly correlated to advanced clinical stage (P<0.05) and lymph node metastasis (P<0.05). miR-103 showed a receiver operating characteristic (ROC) curve area of 84.3%, and a sensitivity of 84% and a specificity of 70% in discriminating breast cancer patients from the control subjects.

CONCLUSIONSerum miR-103 can serve as a potential diagnostic marker for breast cancer and provides useful information of the clinicopathological features of the patients.

Objective To optimize the HT22 cell oxygen-glucose deprivation/re-oxygenation models in hippocampal neurons of mice,discuss the basis of model establishment and test the related parameters.Methods HT22 cell growth curve was plotted by cell counting and cell doubling time was calculated,and then,the oxygen-glucose deprivation time and re-oxygenation time were determined by LDH assay.The CCK-8 assay,cell counting,cell morphology and flow cytometry were performed to further optimize the parameters of the models.Results The HT22 cell doubling time was 17 h 18 min.The oxygen-glucose deprivation time was 18 h and the re-oxygenation was 20 h.CCK-8 assay indicated that absorbance in cells of oxygen-glucose deprivation 18 h/re-oxygenation 20 h (OGD 18 h/R20 h) group was 0.334±0.138,which was significantly lower than that in the control group (0.756±0.026,P＜0.05);cells in the OGD18 b./R20 h group were shrank obviously.Flow cytometry indicated that the percentage of cells in terminal apoptosis or non-viable non-apoptotic cells was 24.56％±5.76％ and that of viable apoptotic cells was 2.63％±0.55％ in the OGD18 h/R20 h group,which were significantly higher than those in the control group,respectively (8.13％±0.87％ and 0.80％±0.10％,/P＜0.05).Conclusion The HT22 cell oxygen-glucose deprivation/re-oxygenation models are successfully established;both oxygen-glucose deprivation time and re-oxygenation time are related to the cell doubling time,and OGD18 h/R20 h can preferably help the establishment;.

ObjectiveTo investigate the effects of dopamine receptor agonist pramipexole and levodopa on emotion and cognition, and mitochondrial membrane potential of rats after global cerebral ischemia-reperfusion injury. MethodsA total of 80 male Sprague-Dawley rats were divided into sham group (n = 20), model group (n = 20), pramipexole group (n = 20) and combined group (n = 20). The latter three groups were used to prepare the model of global cerebral ischemia-reperfusion injury with Pulsinelli's four-vessel occlusion. The pramipexole group was intraperitoneally injected pramipexole 0.5 mg/kg once a day, while the combined group was injected levodopa 50 mg/kg and pramipexole 0.5 mg/kg, for 14 days. Five rats in each group were tested with open field test three, seven and 14 days after modeling; five were tested with Y-maze test seven and 14 days after modeling; five were detected mitochondrial membrane potential three, seven and 14 days after modeling; and five were observed under Nissl's staining14 days after modeling. ResultsCompared with the model group, the number of entries into the central zone (P < 0.05), total distance travelled (P < 0.05) and average velocity (P < 0.05) in the open field test increased in the pramipexole and combined groups seven and 14 days after modeling, duration spent in the central zone increased in the pramipexole and combined groups seven days after modeling (P < 0.05); the rate of spontaneous alternation of Y-maze test increased in the pramipexole and combined groups 14 days after modeling (P < 0.05); mitochondrial membrane potential in hippocampus increased in the pramipexole and combined groups seven and 14 days after modeling (P < 0.05), and it was less in the pramipexole group than in the combined group 14 days after modeling (P < 0.05); and the number of surviving neurons in the hippocampal CA1 increased in the pramipexole and combined groups 14 days after modeling (P < 0.05). ConclusionPramipexole may improve emotion and cognition of rats after global cerebral ischemia-reperfusion injury, and it may be helpful for restoring mitochondrial membrane potential as combining with levodopa.

OBJECTIVE To systematically evaluate the efficacy and safety of novel oral anticoagulants （NOAC） in the treatment of cancer-related venous thromboembolism （VTE） patients. METHODS Retrieved from PubMed， Cochrane Library， Embase， Web of Science， CNKI， and Wanfang database from the establishment of each database to August， 2023， randomized controlled trials （RCTs） about the efficacy of low-molecular-weight heparin （LMWH， control group） versus NOAC （trial group） in the treatment of cancer-related VTE patients were collected. After extracting the data from included clinical studies， meta-analysis was performed by using RevMan 5.0 statistical software. RESULTS A total of 7 RCTs were included， with a total of 3 790 patients. Compared with the control group， the recurrence rate of VTE in the trial group was significantly reduced （RR＝0.65， 95%CI 0.51-0.82， P＝0.000 4）， while the incidence of major bleeding was slightly higher than in the control group， but the difference was not statistically significant （RR＝1.13， 95%CI 0.83-1.53， P＝0.45）. The incidence of clinically relevant non-major bleeding （RR＝1.69， 95%CI 1.34-2.13， P＜0.000 01） and gastrointestinal bleeding （RR＝1.96， 95%CI 1.15-3.34， P＝0.01） in the trial group was significantly higher than in the control group. There was no statistically significant difference in the incidence of intracranial hemorrhage， all-cause mortality， and fatal pulmonary embolism between 2 groups （P＞0.05）. CONCLUSIONS For cancer-related VTE patients， NOAC is superior to LMWH in preventing venous thrombosis recurrence， and is not inferior to LMWH in terms of major bleeding， intracranial hemorrhage， all-cause mortality， and fatal pulmonary embolism.
